CHARLES F. ROPER, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO GEORGE DRAPER & SONS, OF SAME PLACE.

SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 378,906, dated March 6, 1888.

Application filed November 4,1887. Serial No. 254,258.

To aZZ whom it may concern:

Be it known that I, CHARLES F. ROPER, of Hopedale, county of Worcester, and State of- Massachusetts, have invented an Improvement in Supports for Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a spindlebearing in which proper contact may always be maintained between the tapering exterior of the spindle below the whirl and the tapering interior of the bearing, my invention being intended as an improvement upon the bearing shown and described in application,Serial No. 246,994., filed August 15, 1887, by William F. and George A. Draper.

In the application refer-red to the bearingtube has screwed into it a foot having a fixed step,the tube and footbeing united by threaded portions of one engaging threaded portions'of the other, and to adjust the bearing-tube vertically it must be rotated in the surrounding supporting-tube, the foot and step remaining stationary. Herein the step is made as a screw accessible from the top of the bearing-tube through its interior, while the spindle is removed and the step is adjusted vertically, leaving the bearing-tube and foot stationary as to any movement in the direction of its length.

My invention therefore consists, essentially, in a bearing-tube and a support or holder therefor, combined with a screw-threaded step made adjustable vertically or longitudinally in the bearing-tube, while the latter remains stationary, as will be described.

Figure 1 in section shows a spindlesupport embodying my invention and attached to a rail, the latter being also in section, the figure also showing in elevation a small portion of the spindle. Fig. 2 is a top view of the step shown in Fig. 1. Fig. 3 is asectional view of a modified form of my invention; Fig. 4, a top view of the step shown in Fig. 3 removed; and Figs. 5, 6, 7, and 8,views of the keys or devices used to rotate the steps from and through the open upper ends of the bearing-tubes while the latter remain stationary.

The rail A, support or holder B, and nut G are and may be all as usual. The bearingtuhe a, shown in Fig. 1 as inserted in the holder B loosely and surrounded by an elastic or yielding packing, as 1), has connected to it by a pin, b, a foot, 0, which is seated at the lower end of the base in the holder. The interior of the bearing-tube is tapering to fit the tapering exterior of the spindle (I, only a portion of which is shown in Fig. 1, the portion of the spindle not shown being of usual construction. The foot c,connected to and forming thebottom of the bcaring-tube,is provided with a screw-threaded hole, which receives in it a screw-threaded step, e, the upper end of which, as herein shown, is of quadrangular shape to be engaged by a screw-driver or key, as f, slotted or shaped at its lower end to engage the upper end of and rotate the said screw-step, the shank of the screw-driver or key provided with a suitable head, as 3, being extended from its top into and down through the bearing-tube to engage and rotate the said screws to move it vertically with relation to the bearingtube, to thereby enable the top of the screw constituting the step or end bearing for the spindle to be placed at just the proper distance from the upper end of the bearingtube to insure uniform contact between the tapering surfaces of the spindle and bearingtube. rotation by a pin or projection, as g, which enters a groove in the enlarged upper end or head of the tube.

In the modification, Fig. 3, the foot of the tube, or that part thereof below the oilholes, is threaded, and the screw-threaded step is screwed directly into it, the upper end of the screw being shaped, as described of the stepscrew in Fig. 1., to be engaged by the end of the screw-driver or key, Figs. 7 and 8.

I do not desire to limit my invention to making the upper end of the step'screws of the exact shape shown, for it will be obvious that should the said head beef any irregular shape other than round, so that it would be readily engaged by a screw-driver or key, the same result would be gained, and hence my invention would not be departed from.

The bearing'tube is restrained from I clain1 In testimony whereof I have signed my name [0 The spindle having a tapering lower end, a to this specification in the presence of two subbearing-tube having a tapering interior and a scribing witnesses. support or holder therefor, combined with a screw-threaded step having a head accessible CHARLES F. ROPER. by a screw-driver or key through the upper end of the said tube, whereby the step-screw Witnesses: may be adjusted vertically While the tube is WM. W.
